[0034] In the multifunctional tool hammer provided by the utility model, the adjusting arm 2 can be driven by the driving part 5 to move relative to the handle 3 along its axial direction to adjust the overall length of the handle, and at the same time, the clamping gap 4a between the hammer head 11 and the clamping plate 4 can be adjusted, so that the hammer head 11 and the clamping plate 4 can be used as a flexible spanner in combination, and the functions are diverse. Therefore, the scheme can adjust the length of the handle arbitrarily, increase the force arm, and has good practicality; and the user can carry only the multifunctional tool hammer of the scheme to perform the corresponding operations of the claw hammer and the flexible spanner, avoiding the need to carry multiple types of tools, and improving convenience.

[0035] In one embodiment, see Figure 3 and Figure 4 The handle 3 is provided with a mounting channel 3a along its axial direction, and the side wall of the mounting channel 3a is provided with an avoidance groove 3b connected to the outside; the driving part 5 is a driving wheel 51, and the driving wheel 51 is installed in the avoidance groove 3b around the axial direction of the mounting channel 3a, and is provided with a driving screw hole 51a connected to the mounting channel 3a. The outer wall of the adjusting arm 2 is provided with an external thread, and is penetrated by the mounting channel 3a and the driving screw hole 51a, so that it can move relative to the handle 3 along its axial direction when the driving wheel 51 rotates.

[0036] In this embodiment, the adjusting arm 2 is driven to move along the axial direction of the handle 3 by rotating the driving wheel 51, so that the overall length of the handle and the clamping gap 4a can be adjusted.

[0038] In this embodiment, after the position of the adjusting arm 2 is adjusted, the locking bolt 8 is tightened to limit the rotation of the driving wheel 51 relative to the handle 3, thereby improving the stability of the hammer body 1. When the position of the adjusting arm 2 needs to be adjusted, only the locking bolt 8 needs to be loosened, which is simple and convenient to operate.

[0039] In one embodiment, the inner wall of the installation channel 3a is provided with a limiting groove 3c along its axial direction, and a limiting rod 6 is provided at one end of the adjustment arm 2 away from the body 12. The limiting rod 6 is slidably arranged in the limiting groove 3c along the axial direction of the installation channel 3a.

[0040] In this embodiment, a limit rod 6 and a limit groove 3c are arranged between the installation channel 3a and the adjustment arm 2. The limit rod 6 and the limit groove 3c cooperate to limit the axial rotation of the adjustment arm 2 around the installation channel 3a, thereby ensuring that the clamping gap 4a between the hammer head 11 and the clamping plate 4 does not need to be manually adjusted and aligned, thereby improving convenience, so that when the driving wheel 51 rotates, the adjustment arm 2 automatically moves in a straight line.

[0041] In one embodiment, the limit groove 3c is set at an opening on one side away from the installation channel 3a, and the handle 3 is provided with a scale line at the opening end corresponding to the limit groove 3c. The scale line is arranged along the axial direction of the installation channel 3a. The limit rod 6 extends out of the opening of the limit groove 3c and cooperates with the scale line to indicate the size of the clamping gap 4a.

[0042] In this embodiment, the user can read the size of the clamping gap 4a by observing the position of the scale line corresponding to the limit rod 6, thereby clamping a workpiece of corresponding size, thereby improving practicality.

[0043] In one embodiment, an end of the adjusting arm 2 away from the body 12 is provided with a mounting screw hole 2a, and the limiting rod 6 is provided with a threaded end corresponding to the mounting screw hole 2a, and the threaded end is screwed into the mounting screw hole 2a.

[0046] In this embodiment, the sliding shaft 52 is slidably arranged in the annular groove 3e, so that the rotation of the driving wheel 51 is relatively smooth and stable, which is convenient for user operation. It should be noted that in this solution, the outer wall of the driving wheel 51 is provided with anti-slip stripes, and at least partially extends out of the notch of the avoidance groove 3b.

[0047] In one embodiment, the side wall of the avoidance groove 3b having the annular groove 3e is also provided with a connecting groove 3f, and the connecting groove 3f connects the notch of the avoidance groove 3b and the annular groove 3e, and the sliding shaft 52 can be separated from the annular groove 3e from the connecting groove 3f.

[0048] In this embodiment, when the driving wheel 51 needs to be removed, the sliding shaft 52 is rotated to a position corresponding to the connecting groove 3f, and then the driving wheel 51 is moved along the notch position of the connecting groove 3f, so that the driving wheel 51 can be taken out of the avoidance groove 3b.

[0049] In one embodiment, an indicator mark is provided on the outer wall surface of the driving wheel 51, and a matching mark is provided at the notch of the avoidance groove 3b. When the sliding shaft 52 slides to the position of the connecting groove 3f, the indicator mark is opposite to the matching mark.

[0050] In this embodiment, when the indicator mark is aligned with the matching mark, it means that the sliding shaft 52 has slid to the position corresponding to the connecting groove 3f, which is convenient for the operator to disassemble and install the driving wheel 51, and improves practicality. It should be noted that in this solution, the indicator mark is a colored indicator point set on the driving wheel 51, and similarly, the matching mark is a colored indicator point set at the notch of the handle 3 corresponding to the connecting groove 3f. Specifically, the indicator mark is a red dot, and the matching mark is a blue dot.

[0052] In this embodiment, a rubber pad 7 is provided at the portion of the connecting groove 3f close to the annular groove 3e to provide a certain barrier to the sliding shaft 52 and prevent the sliding shaft 52 from accidentally detaching from the annular groove 3e; at the same time, it also provides a certain sealing effect on the annular groove 3e to prevent foreign matter from entering the annular groove 3e from the connecting groove 3f.

[0053] In one embodiment, two opposite side walls of the clamping gap 4a are respectively provided with bottom tooth plates.

[0054] In this embodiment, bottom tooth plates are respectively arranged on the two opposite side walls of the clamping gap 4a, that is, bottom tooth plates are respectively arranged on the inner sides of the clamping plate 4 and the hammer head 11, so as to improve the bite ability of the clamping plate 4 and the hammer head 11 on the workpiece. Specifically, in this solution, the inner sides of the clamping plate 4 and the hammer head 11 are both arranged as arc-shaped concave surfaces.

[0055] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0056] This solution drives the adjustment arm 2 to move relative to the handle 3 along its axial direction by rotating the driving wheel 51 to adjust the length of the handle and the size of the clamping gap 4a. After the length of the handle or the size of the clamping gap 4a is adjusted, the locking bolt 8 is tightened to limit the driving rotation and improve stability, so that the force arm length of the multifunctional tool hammer is adjustable, and the corresponding operations of the claw hammer and the adjustable spanner can be performed, which is more practical. In addition, when the components are damaged, the limit rod 6, the adjustment arm 2, the driving wheel 51 and the handle 3 can be disassembled, so that the operator can repair and replace the corresponding components, which improves convenience.
