A: Disclosed is clothing capable of being transformed into a bag, which is clothing capable of being transformed. The clothing comprises a clothing body. The clothing body consists of a clothing back part (1), a left front portion (2), a right front portion (3), sleeves (4), and a collar (5). An interlayer (6) is disposed in the clothing body. An upper end and left and right sides of the interlayer (6) are closed, and a lower end of the interlayer (6) is open. Lower end portions of an outer layer body (61) and an inner layer body (62) forming the interlayer are each provided with an accommodating portion (61a, 62a). A carrying strap (7) is disposed in each accommodating portion (61a, 62a). The accommodating portion (61a, 62a) has an upper end closed and a lower end open, and the open portion is sealed by using a connecting member (8) easy to be opened. After the inner layer body (62) and the outer layer body (61) of the interlayer (6) are folded upward, the outer layer body (61), the inner layer body (62), and the closed upper end and left and right sides of the interlayer (6) together form a bag, and the clothing body is accommodated in the bag. The clothing is capable of being transformed, the interlayer (6) is disposed in the clothing back part (1), the carrying straps (7) are disposed and accommodated in the accommodating portions (61a, 62a) at the lower end portions of the outer layer body (61) and the inner layer body (62) of the interlayer (6). The accommodating portion (61a, 62a) is sealed by using velcro or another connecting member (8) easy to be opened or closed. Therefore, no redundant structure can be seen outside the clothing, thereby not affecting the appearance of the clothing. The connecting portion of the carrying strap (7) in the accommodating portion (61a, 62a) does not contact the human body, thereby preventing a user from feeling uncomfortable.
B: An easy-to-adjust food barbecuing device, relating to the field of barbecuing devices. The easy-to-adjust food barbecuing device comprises a housing (1); vertical rods (2) are inserted at two sides of the top of the housing (1); one end, close to the housing (1), of each vertical rod (2) penetrates through the top of the housing (1) and extends inside the housing (1); the top of the vertical rod (2) is rotatably connected with a sleeve (3), and the tops of two sleeves (3) are fixedly connected by means of a box body (4); the left side of the box body (4) is communicated with an air inlet pipe (5); a screw rod (6) is inserted at the top of the housing (1). By providing the vertical rods (2), the sleeves (3), the screw rod (6), a sliding rail (7), a sliding plate (8), a spring (9), a nut (10), a rotating disc (12), a protruding block (13), and a bushing (14), the easy-to-adjust food barbecuing device achieves the effect of adjusting the food barbecuing device, thereby facilitating the use of a user, and therefore also improving the working efficiency of the food barbecuing device.
C: A shoe press, comprising a shoe sleeve roller (7) and a shoe pressing pairing roller (8), the shoe sleeve roller (7) comprising a supporting beam (4) and a shoe sleeve (13) rotatably mounted on the supporting beam (4), wherein a shoe plate (1) arranged in the shoe sleeve roller (7) and hydraulic loading devices are further comprised, the hydraulic loading devices are arranged between the supporting beam (4) and the shoe plate (1), the hydraulic loading devices are arranged in two rows in the width direction of the shoe plate (1), each hydraulic loading device is connected to the corresponding side of the shoe plate (1), and the two rows of hydraulic loading devices are connected to independent oil intake channels respectively and are used for pressurizing two sides of the shoe plate (1) respectively.
D: A housing (100) for a ski boot, and a ski boot comprising the housing (100). The housing (100) comprises a left part (120) and a right part (130). The left part (120) and the right part (130) can switch between a state when the left part (120) and the right part (130) are separated from each other by a certain distance, and a state when the left part (120) and the right part (130) are tightly closed. In the separated state, the left part (120) and the right part (130) are separated relative to each other and can pivot relative to each other. The housing (100) further comprises a locking mechanism (150, 160). The locking mechanism (150, 160) comprises a pull line (151, 161) and a lock device (152, 162). The lock device (152, 162) can roll up the pull line (151, 161) and tightly pull the pull line (151, 161) so as to maintain the housing (100) in the closed state, or the lock device (152, 162) can release the pull line (151, 161) so as to allow the housing (100) be in the separated state. Hence, the housing (100) can be conveniently placed at an open position so as to take an inner boot (200) out from the housing (100) for facilitating walking of a skier. Moreover, when required, the inner boot (200) can be easily put into the housing (100) and the housing (100) is locked, so that the ski boot is used like a normal dual-plate ski boot.
