This utility model belongs to the field of rebar processing technology and discloses a rebar straightening, length-fixing, shearing, and unloading device. It includes a rebar straightening mechanism and an unloading mechanism. The rebar straightening mechanism includes a machine body, on which a straightening roller and a shearing assembly are mounted. The straightening roller includes a roller body with multiple straightening seats. Rollers are rotatably mounted on the straightening seats, and the rollers are obliquely positioned. Straightening holes are provided between the rollers and the straightening seats to allow rebar to pass through. Adjacent rollers face opposite directions and are adjustable relative to the roller body. The roller body can rotate relative to the machine body. The shearing assembly is located downstream of the straightening roller to cut the rebar. The unloading mechanism is located downstream of the rebar straightening mechanism and includes a frame and a length-fixing component. The length-fixing component moves along a first direction on the unloading mechanism to fix the length of the rebar. The first direction is perpendicular to a second direction, thus solving the problems of high wear, poor versatility, and high energy consumption in rebar straightening; it also solves the problem of low shearing efficiency.

The invention relates to a motor vehicle lock (1) having a locking mechanism (2) with a pivotable locking bolt (3) and a pivotable locking pawl (4) associated with the locking bolt (3). It is proposed that the motor vehicle lock (1) has a spring assembly (11) and a pivotable preloading lever (13) preloaded or preloadable in a preloading direction (12) by the spring assembly (11), which preloading lever is in a preloading transmission mechanism engagement (14) or can be brought into a preloading transmission mechanism engagement with the locking pawl (4), and the preloading transmission mechanism engagement (14) is designed such that the locking pawl (4) is preloaded or preloadable by the spring assembly (11) in a falling direction (15) with a locking pawl preloading force by means of the preloading transmission mechanism engagement (14), and the preloading transmission mechanism engagement (14) is not self-locking from the locking pawl (4) to the preloading lever (13) in a main locking state and / or in a prelocking state.

This utility model belongs to the field of trolley technology, and specifically relates to a trolley that facilitates straight-line travel. It includes a balance scooter and a trolley body, connected by a connecting frame. The connecting frame is detachably connected to the trolley body and rotatably connected to the balance scooter. The balance scooter has a positioning groove, and the connecting frame has a positioning element and an elastic element. The elastic element drives the positioning element to engage with the positioning groove, fixing the balance scooter and the connecting frame relatively, thus allowing the trolley to maintain straight-line travel or maintain a certain angle of rotation. Under external force, the positioning element can move relative to the positioning groove, allowing the balance scooter and the connecting frame to rotate relative to each other, thus enabling the trolley to turn flexibly. The purpose of this utility model is to provide a user-friendly trolley that facilitates straight-line travel.

A double-point supporting device used during shoe upper and shoe tree glue brushing comprises a base, and a main supporting component and an auxiliary supporting component are arranged on the base. The main supporting component comprises a first supporting column, the lower end of the first supporting column is connected to the base, and the upper end of the first supporting column is in spherical hinge connection with an inserting rod through a universal ball joint. The auxiliary supporting component comprises a second supporting column, the second supporting column is obliquely arranged facing the side of the main supporting component, the lower end of the second supporting column is connected to the base, and the upper end of the second supporting column is rotationally connected with a supporting ball head. Compared with the prior art, the shoe tree has the technical effects that the shoe tree is provided with a front support and a rear support, the rotation of the shoe tree is not affected, the force of a wrist is weakened, and the glue brushing operation is facilitated.

The utility model relates to the technical field of disassembling and assembling tools, and discloses a tool wrench which comprises a first handle and a second handle, a plurality of protruding blocks are fixedly connected to the top of the second handle, a two-way lead screw is in threaded connection with the side, close to the second handle, of the first handle, a rotating ring is fixedly connected to the outer portion of the two-way lead screw, and the rotating ring is in threaded connection with the top of the second handle. A notch is formed in one side of the second handle, limiting assemblies used for limiting parts are arranged at the two ends of the side, close to the second handle, of the first handle, an adjusting assembly is arranged on one side of the first handle, and each limiting assembly comprises two connecting rods. The two connecting rods are slidably connected to the two ends of the sides, close to each other, of the first handle and the second handle correspondingly. According to the utility model, the tool can be flexibly used in a narrow space, the tool is more suitable for complex scenes, in addition, the distance can be adjusted by reducing the force through the lever effect, the operation is more labor-saving, and the working efficiency and the user experience are greatly improved.
