A conventional socket suspension device has an anti-theft mechanism including an elastic piece. The elastic piece is deformed and disposed in the socket to position the socket. However, to install the socket or to detach the socket, a user has to press the elastic piece, so operation of the suspension device is quite difficult.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide an anti-theft suspension device for socket which is easy to operate.
To achieve the above and other objects, an anti-theft suspension device for socket is provided. The suspension device is adapted for receive a socket having a sleeve hole wherein the inner wall of the sleeve hole is formed with a positioning notch. The suspension device includes a main body, a socket holder, and a locking mechanism.
The socket holder includes a seat and a receiving member. The seat is disposed on the main body. The receiving member is rotatably disposed on the seat and is adapted for the socket to sleeve onto. The receiving member is able to rotate with respect to the seat around a rotation axis between a locking position and an unlocking position. The socket holder has a positioning bump located on one of the seat and the receiving member. When the receiving member is rotated between the locking position and the unlock position, the positioning bump is moved between a first position and a second position. When the positioning bump is located at the first position, the positioning bump is exposed outside the socket holder to be received in the positioning notch of the socket so that the socket is unable to leave the socket holder freely. When the positioning bump is located at the second position, the positioning bump is not exposed outside the socket holder and is not received in the positioning notch of the socket so that the socket is able to leave the socket holder freely. The locking mechanism alternatively inhibits the receiving member from rotating with respect to the seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIG. 1 to FIG. 3 and FIGS. 3A, 3B, and 3C, an anti-theft suspension device for socket is provided in the present invention. The suspension device is adapted for received a socket 50 having a sleeve hole wherein the inner wall of the sleeve hole is formed with a positioning notch 51. The anti-theft suspension device for socket of the present invention includes a main body 10, a socket holder 20, a locking mechanism, and a limitation mechanism.
The main body 10 is substantially elongated plate-shaped, and a longitudinal direction is defined by the main body 10. Two ends of the main body 10 along the longitudinal direction are connected with a suspension member 30 and a cover 40. Two tracks 11 are formed at two sides of the main body 10 along a width direction. More specifically, two ends of the main body 10 along the longitudinal direction are formed with an insertion hole 12 respectively. The suspension member 30 is formed with a suspension hole 31 at an end and an insertion piece 32 at an opposite end. The cover 40 is also formed with an insertion piece 41. The suspension member 30 and the cover 40 are positioned to the main body 10 by inserting the insertion pieces 32, 41 into the insertion hole 12.
The socket holder 20 includes a seat 21 and a receiving member 22. The seat 21 is disposed on the main body 10. The receiving member 22 is rotatably disposed on the seat 21 and is adapted for being sleeved onto by the socket 50 with its sleeve hole. The receiving member 22 is able to rotate with respect to the seat 21 around a rotation axis between a locking position and a unlock position. The socket holder 20 further includes a positioning bump 215 located on one of the seat 21 and the receiving member 22. When the receiving member 22 is rotated between the locking position and the unlock position, the positioning bump 215 is moved between a first position and a second position. When the positioning bump 215 is located at the first position, the positioning bump 215 is exposed outside the socket holder 20 to buckle the positioning notch 51 of the socket 50 so that the socket 50 is unable to leave the socket holder 20 freely. When the positioning bump 215 is located at the second position, the positioning bump 215 is not exposed and is not received in the positioning notch 51 of the socket 50 so that the socket 50 is free to leave the socket holder 20. In the present embodiment, the seat 21 is formed with two wing pieces 214, and a sliding space is defined between the two wing pieces 214. The two wing pieces 214 are slidably disposed on the two tracks 11 of the main body 10 so that part of the main body 10 is received in the sliding space. The seat 21 is formed with a first plinth piece 211 and a second plinth piece 212 arranged spacedly. The first plinth piece 211 and the second plinth piece 212 are connected by a connecting piece 213 to be substantially U-shaped. The positioning bump 215 is protrudingly formed on a face of the first plinth piece 211 opposite to the second plinth piece 212. The receiving member 22 includes a base 221 and a shelter 222. The base 221 is rotatably disposed on the seat 21, and the shelter 222 is adapted for receiving the first plinth piece 211, the second plinth piece 212, and the connecting piece 213. The shelter 222 includes a plurality of lateral walls 2221 and a top wall 2222. One of the lateral walls 2221 is formed with an opening 2223. When the positioning bump 215 is located at the first position, the positioning bump 215 is exposed via the opening 2223 to buckle the positioning notch 51 of the socket 50. When the positioning bump 215 is located at the second position, the positioning bump 215 is deviated from the opening 2223 and is located inside the shelter 222. More specifically, the shelter 222 has four lateral walls 2221 to be cuboid-shaped. The top wall 2222 of the shelter 222 is substantially square. The rotation axis penetrates the center of the top wall 2222. When the positioning bump 215 is located at the second position, the positioning bump 215 is located between two adjacent lateral walls 2221 and is located on a diagonal line of the shelter 222 so that the positioning bump 215 is received in the shelter 222.
In addition, the top wall 2222 of the shelter 222 is formed with a through slot 2224, and the inner wall of the through slot 2224 is formed with an annular groove 2225. The connecting piece 213 is formed with a protrusion 216 on a face opposite to the seat 21, and the protrusion 216 is formed with an annular rib 2161. The protrusion 216 is inserted through the through slot 2224, and the annular rib 2161 is rotatably received in the annular groove 2225 so that the receiving member 22 is unable to be separated from the seat 21 freely.
The locking mechanism alternatively inhibits the receiving member 22 from rotating with respect to the seat 21. In the present embodiment, the base 221 of the receiving member 22 has a positioning hole 2211, and the seat 21 has a through hole 217. When the receiving member 22 is located at the locking position, the positioning hole 2211 overlaps the through hole 217. The locking mechanism includes a locking stick 60. When the locking stick 60 is inserted through the positioning hole 2211 and the through hole 217, the receiving member 22 is unable to rotate with respect to the seat 21 and is positioned at the locking position. The limitation mechanism is detachably disposed on the main body 10 to position the locking stick 60 to inhibit the locking stick 60 from leaving the main body 10. More specifically, the suspension member 30 and the cover 40 are formed with limitation grooves 33, 42 at the faces toward each other. Two opposite ends of the locking stick 60 are inserted into the limitation grooves 33, 42 respectively so that the locking stick 60 is restricted between the suspension member 30 and the cover 40. To release the locking stick 60, at least one of the suspension member 30 and the cover 40 has to be detached from the main body 10.
In use, the locking stick 60 is separated from the socket holder 20 at first. When the receiving member 22 is rotated to the unlock position, the socket 50 is able to be sleeved onto the shelter 222 of the receiving member 22. Thereafter, to position the socket, one can rotate the receiving member 22 to the locking position to make the positioning bump 215 buckle the positioning notch 51 of the socket 50. And then, insert the locking stick 60 through the positioning hole 2211 and the through hole 217 and make the locking stick 60 be restricted between the suspension member 30 and the cover 40, and the operation is completed. As a result, the socket 50 is unable to be detached from the receiving member 22 freely, and the receiving member 22 is kept at the locking position due to the locking stick 60. Furthermore, the locking stick 60 is restricted between the suspension member 30 and the cover 40 so that the locking stick 60 is unable to be detached easily.
To detach the socket 50, one of the suspension member 30 and the cover 40 is detached first to removing the locking stick 60, and the receiving member 22 has to be rotated to the unlock position to make the positioning bump 215 move inward. Thereby, the socket 50 is able to be detached from the receiving member 22.
