## Background
TECHNICAL FIELD
The present invention relates to a buttstock structure for a toy gun and, in particular, to a length adjustable buttstock structure for a toy gun.
BACKGROUND
When using airsoft guns, the size and shape of the face of each player is not the same, and consequently, the airsoft guns may not contact the face properly to well support the face. In addition, since each player has different gripping methods and habits, a buttstock has to be adjusted to a suitable length so that the buttstock may contact against the chest of the player when the airsoft gun is changed to a rifle. There are conventional length adjustable buttstock structures in the market. The conventional length adjustable buttstock structure is operated by two elements: a handle and a fastening structure. When to extend the buttstock, first the fastening structure is released to separate the buttstock structure from a barrel (which typically called “Buffer Tube”), then the handle is pressed to make the buttstock away from a gear portion in the barrel, and thereby extension or shorten of the buttstock is completed (the foregoing descriptions relate to the known length adjustable buttstock structures in the market). Although the length of the buttstock can be adjusted using the aforesaid structure, the structure is complicate and has too many components, thereby resulting in high assembling and production costs and other problems.
In view of the foregoing, the inventor made various studies to improve the above-mentioned problems by providing a simple structure to adjust the buttstock or a cheek piece, so as to enhance the practical utility in the industries.
SUMMARY
It is an object of the present invention to provide a buttstock structure for a toy gun, which has a simple structure and can be adjusted readily and quickly.
Accordingly, the present invention provides a buttstock structure for a toy gun, for collaborating with a gun body. The gun body comprises an extension member connected to the gun body. The extension member is formed with a plurality of retaining troughs. The buttstock structure includes a buttstock body and an adjusting trigger. The buttstock body includes a chamber accommodating the extension portion, a latch selectively engaged with a respective one of the retaining troughs, and a latch recess accommodating the latch, wherein a retaining pin is inserted in the latch and protrudingly disposed on a side wall of the latch recess. The adjusting trigger is movably connected with the buttstock body. The adjusting trigger includes a handle and a linking member connected to the handle. Two inclined slots for containing the retaining pin is formed at one end of the linking member. When the adjusting trigger moves away from the latch, the retaining pin moves along the two inclined slots to drive the latch to be removed from the retaining trough, and thereby the buttstock body is moved with respect to the extension portion.
