The front of the first U-shaped frame 22 is fixedly connected to the wrench handle 3, and the back of the second U-shaped frame 23 is fixedly connected to the wrench head 1.
[0028] Reference Figure 3 , also includes a shell 24, a control board 25, and a display 26. The shell 24 is fixedly installed on the top of the wrench handle 3, the control board 25 is arranged inside the shell 24, the display 26 is installed on the top of the shell 24, and is electrically connected to the control board 25. The control board 25 is electrically connected to the static torque sensor 21. When the static torque sensor 21 detects the torque, it sends a signal to the control board 25, and the detected torque is displayed in real time through the display 26, so that the operator can have a more intuitive understanding of the detection data.
[0029] Reference Figure 3 , and also includes a power battery 27. The power battery 27 is fixedly installed at the bottom of the wrench handle 3. The power battery 27 is electrically connected to the display 26 and the static torque sensor 21 through the control board 25.

[0030] Reference Figure 4The hidden nail remover 5 includes a horn nail removing block 51 and a shaft column 52. An inner groove is provided at one end of the wrench handle portion 3 away from the torque detection component 2. The shaft column 52 is fixedly connected in the inner groove of the wrench handle portion 3. The horn nail removing block 51 is movably sleeved on the side wall of the shaft column 52. The inner groove a surface and the horn nail removing block 51b surface fit together to form an angle positioning for the horn nail removing block 51. By moving the horn nail removing block 51 to rotate it around the axis of the shaft column 52, the horn nail removing block 51 can be flipped into the inner groove of the wrench handle portion 3, thereby achieving a hidden effect. When in use, the horn nail removing block 51 is flipped out, and the horn nail removing block 51b surface and the inner groove a surface fit together and move against each other to limit the outward turning angle of the horn nail removing block 51. At this time, the nail removing operation can be performed through the horn nail removing block 51.
[0031] Reference Figure 4 The horn nail removing block 51 is closely fitted with the side wall of the shaft column 52, so that the horn nail removing block 51 has a certain friction force on the side wall of the shaft column 52. When the horn nail removing block 51 is hidden in the inner groove, it can be prevented from rotating and being exposed without external force.
[0032] Reference Figure 5 The hammer assembly 4 includes a protrusion 41, a U-shaped connecting block 42, a main hammer member 45, and a rubber block 46. The protrusion 41 is provided with a slide groove on the front and back sides, and a slider 43 is slidably sleeved in the two slide grooves. The front and back sides of the inner wall of the U-shaped connecting block 42 are fixedly connected to the two sliders 43. The protrusion 41 is connected to the U-shaped connecting block 42 through the rubber block 46. The main hammer member 45 is fixedly connected to one end of the U-shaped connecting block 42. When the hammer assembly 4 is hammering, the main hammer member 45 contacts the object, so that the U-shaped connecting block 42 moves and applies a force to the rubber block 46. Through the material characteristics of the rubber block 46, a certain shock-absorbing effect can be achieved, thereby making the hammer assembly 4 have a shock-absorbing effect during the hammering process.
[0033] Reference Figure 5 The protrusion 41 is provided with an axial groove on one side facing the U-shaped connecting block 42, and an anti-slip column 44 is slidably sleeved in the axial groove. The anti-slip column 44 passes through the rubber block 46 and is connected to the U-shaped connecting block 42. The anti-slip column 44 can prevent the rubber block 46 from falling off.
[0034] Reference Figure 6The auxiliary handle assembly 6 includes a main auxiliary handle 61, a polygonal insert 62, a connecting column 63, and a positioning disk 64. A polygonal notch adapted to the polygonal insert 62 is opened on the top of the wrench handle portion 3, and a positioning hole is set at the bottom of the wrench handle portion 3. The positioning hole and the polygonal notch are connected through a through hole. One end of the bottom of the main auxiliary handle 61 is connected to the polygonal insert 62, and the polygonal insert 62 is connected to the positioning disk 64 through the connecting column 63. The positioning disk 64 is slidably sleeved in the positioning hole, and the connecting column 63 is slidably sleeved in the through hole. The diameter of the positioning disk 64 is larger than the diameter of the through hole. When in use, the main auxiliary handle 61 is rotated to change the orientation of its other end, so that the auxiliary handle assembly 6 can achieve a flipping effect to extend and lengthen the wrench handle portion 3, and then the main auxiliary handle 61 is pressed to make the polygonal insert 62 embedded in the polygonal notch, thereby the main auxiliary handle 61 can be angularly positioned. At this time, the wrench can be used by applying force to the auxiliary handle assembly 6 to achieve the effect of lever growth and labor saving, and the auxiliary handle assembly 6 can be prevented from falling off through the positioning disk 64.
[0035] The working principle of the utility model is as follows: when in use, the wrench head 1 is used to screw bolts, nuts and other screwing parts, the hammer assembly 4 can be used to hammer nails, and the hidden nail remover 5 can be opened to remove nails. The above-mentioned components are arranged to improve the functionality of the wrench;
[0036] When the wrench head 1 is used to tighten the screw bolts, nuts and other screw parts, the torque is applied by holding the wrench handle 3. At this time, the wrench head 1 applies a positive or reverse rotational force to the bottom of the static torque sensor 21 under the connection effect of the second U-shaped frame 23, and the wrench handle 3 positions the static torque sensor 21 under the connection effect of the first U-shaped frame 22. Therefore, the torque can be detected by the static torque sensor 21 during the operation of the wrench, so that the operator can accurately control the torque when tightening the screw bolts, nuts and other screw parts, and the first U-shaped frame 22 and the second U-shaped frame 23 can be connected to form a whole through the first rotating column 28 and the second rotating column 29 to ensure the structural stability;
[0037] When dealing with an overtightened part, the auxiliary handle assembly 6 can be flipped by adjusting its installation angle so that the auxiliary handle assembly 6 can be used as an extension handle of the wrench handle portion 3, thereby achieving an effect of lengthening the wrench lever, thereby saving effort when tightening an overtightened part.
