Description

Technical field:

[0001] The utility model relates to the technical field of ratchet wrenches, and more specifically to a flip-type ratchet wrench. Background technology:

[0002] The ratchet wrench can provide the user with the function of free-wheeling and pulling back without having to remove the wrench from the fastener in a limited operating space, thereby improving the working efficiency. The development of the ratchet wrench has become a fairly mature technology.

[0003] Existing ratchet wrenches, such as a 120-tooth high-precision and high-torque ratchet wrench with Chinese patent application number 201911405062.X, include a handle body, a handle body head is formed on the upper part of the handle body, and the handle body and the handle body head are directly formed together. The length is generally long to reduce the force required for its operation. However, its long length makes it inconvenient to carry, and it needs to be placed in a bag, which takes up a lot of space. It cannot be placed in a pocket or the like. As a result, when checking the equipment anywhere and finding a problem, it is not convenient to immediately remove the corresponding bolts for inspection or repair. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a flip-type ratchet wrench, which can flip the handle to be above the top surface of the ratchet head body to achieve folding, thereby shortening its length and being able to be placed in a pocket for easy carrying and storage, reducing space occupancy, and can be used at any time when carried around, thereby being able to cope with sudden maintenance and other problems.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A flip ratchet wrench includes a ratchet head body, a connecting block extending upward is provided in the middle of the rear end top surface of the ratchet head body, and a flip handle is movably connected to the connecting block. The handle is flipped over and positioned above the top surface of the ratchet head body to achieve folding, thereby shortening its length and being able to be placed in a pocket for easy carrying and storage.

[0007] A connecting through hole extending left and right is formed in the middle of the connecting block, a mounting slot extending backward is formed in the middle of the front end surface of the handle, the top and bottom surfaces of the mounting slot extend out of the top and bottom surfaces of the front end of the handle, the connecting block is inserted into the mounting slot, and through holes extending left and right and extending outward are formed on the left and right side walls of the mounting slot, the clamping spring is inserted into the connecting through hole, the two steel ball parts are located in the inner ends of the corresponding through holes, and the remaining parts of the steel balls are located in the ends of the connecting through holes.

[0008] The through hole is a stepped through hole, the inner end of which is a large diameter hole section and the outer end is a small diameter hole section. The steel ball part is in the large diameter hole section, and the side wall at the corresponding end of the steel ball presses against the arc-shaped wall surface formed on the inner side of the end surface where the large diameter hole section and the small diameter hole section are connected, and the other end of the steel ball presses against the end of the clamping spring.

[0009] With this structure, after the handle is pulled backward, the compression spring can be deformed, so that the steel ball is moved out of the through hole, thereby achieving separation of the two.

[0010] A transverse connecting rod is formed or fixed in the middle of the left and right side walls of the connecting block, and a vertical mounting slot extending backward and a transverse slot extending backward are formed in the middle of the front end surface of the handle. The top and bottom surfaces of the mounting slot extend out of the top and bottom surfaces of the front end of the handle, and the left and right ends of the transverse slot extend out of the left and right side walls of the front end of the handle. The connecting block is inserted into the mounting slot, and the mounting slot divides the front end of the handle into two left and right connecting parts. The transverse slot forms a transversely extending connecting slot in the middle of the front ends of the two connecting parts, and the transverse connecting rod is inserted into the corresponding connecting slot.

[0011] A vertically extending screw-in hole is formed on the top or bottom surface at the front of the connecting slot, and the ball screw is screwed in the screw-in hole. The steel ball portion of the ball screw extends out of the top or bottom surface of the connecting slot and is located at the front of the corresponding transverse connecting rod.

[0012] The outstanding effects of the utility model are:

[0013] The handle can be flipped over and positioned above the top surface of the ratchet head body to achieve folding, thereby shortening its length and being placed in a pocket for easy carrying and storage, reducing space occupancy, and can be used at any time when carried with you, thereby being able to cope with sudden maintenance and other issues.

[0020] Example 1, see Figures 1 to 4 As shown, a flip ratchet wrench includes a ratchet head body 10, in which components such as a ratchet, a pawl, and a commutator are installed. These components are the same as the structures of existing conventional ratchet wrenches and are well-known structures, so they are not described in detail.

[0021] Furthermore, a connecting head 12 provided in the middle of the bottom surface of the ratchet installed in the ratchet head body 10 extends out of the bottom surface of the ratchet head body 10 , and a connecting block 11 extending upward is formed in the middle of the top surface of the rear end of the ratchet head body 10 .

[0022] A connecting through hole 111 extending left and right is formed in the middle of the connecting block 11, and a mounting slot 21 extending backward is formed in the middle of the front end surface of the handle 20. The top and bottom surfaces of the mounting slot 21 extend out of the top and bottom surfaces of the front end of the handle 20. The connecting block 11 is inserted into the mounting slot 21, and the left and right side walls of the mounting slot 21 are formed with through holes 22 extending left and right and extending outward. The compression spring 1 is inserted into the connecting through hole 111, and parts of the two steel balls 2 are located in the inner ends of the corresponding through holes 22, and the remaining parts of the steel balls 2 are located in the ends of the connecting through holes 111.

[0023] The through hole 22 is a stepped through hole, the inner end of which is a large diameter hole section and the outer end is a small diameter hole section. The steel ball 2 is partially located in the large diameter hole section, and the side wall at the corresponding end of the steel ball 2 is pressed against the arc-shaped wall surface formed on the inner side of the end surface where the large diameter hole section and the small diameter hole section are connected, and the other end of the steel ball 2 is pressed against the end of the compression spring 1. During manufacturing, the corresponding end of the steel ball 2 is fixed on the end of the compression spring 1.

[0024] This structure enables the handle 20 of this embodiment to be turned over and pressed against the top surface of the ratchet head body 10 when not in use, thereby reducing its length and making it easier to carry;

[0025] At the same time, the handle 20 and the ratchet head body 10 can be separated. It only needs to pull the handle 20 backwards to compress the compression spring 1 and retract the two steel balls 2 into the connecting through hole 111. At this time, the handle 20 can be separated from the ratchet head body 10.

[0026] Furthermore, the handle 20 includes a front end connecting portion 23 and a rear end rod body portion 24, the front end of the rear end rod body portion 24 is formed on the rear end surface of the front end connecting portion 23, and a mounting slot 21 extending backward is formed in the middle of the front end surface of the front end connecting portion 23, and the top and bottom surfaces of the mounting slot 21 extend out of the top and bottom surfaces of the front end connecting portion 23.

[0027] The outer side walls of the front and rear parts of the rear end rod body 24 are formed with annular grooves 241, and the inner side walls of the annular grooves 241 are arc-shaped walls. The two annular grooves 241 can facilitate the gripping of the rear end rod body 24 by hand.

[0028] Furthermore, the front wall surface of the front end connecting portion 23 is an arc-shaped wall surface.

[0029] Embodiment 2, as Figure 5 and Figure 6 As shown, a transverse connecting rod 112 is formed or fixed in the middle of the left and right side walls of the connecting block 11, and the front end of the handle 20 is a front end connecting part 23, and a vertical mounting slot 21 extending backward and a transverse slot extending backward are formed in the middle of its front end surface. The top and bottom surfaces of the mounting slot 21 extend out of the top and bottom surfaces of the front end of the front end connecting part 23, and the left and right ends of the transverse slot extend out of the left and right side walls of the front end of the front end connecting part 23 of the handle 20. The connecting block 11 is inserted into the mounting slot 21, and the mounting slot 21 divides the front end of the handle 20 into two left and right connecting parts 25. The transverse slot forms a transversely extending connecting slot 251 in the middle of the front end of the two connecting parts 25, and the transverse connecting rod 112 is inserted into the corresponding connecting slot 251.

[0030] A vertically extending screw-in hole is formed on the top or bottom surface at the front of the connecting slot 251, and the ball screw 252 is screwed into the screw-in hole. The steel ball portion of the ball screw 252 extends out of the top or bottom surface of the connecting slot 251 and is located at the front of the corresponding transverse connecting rod 112.

[0031] The rest is the same as in Example 1. With this structure, the handle 20 is movably connected to the transverse connecting rod 112 and can be flipped. At the same time, when pulled backward, the steel ball of the ball screw 252 can be retracted into the inside when the transverse connecting rod 112 moves forward, so that the handle 20 can be separated from the ratchet head body 10.

[0032] This embodiment is easy to carry, occupies little space, and is convenient to store. It can be used at any time to cope with sudden maintenance and other problems.

[0033] Of course, when carrying it with you, you need to put a few commonly used sleeves in your pocket and install them when you need to use them.
