[0022] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 The multifunctional combined striking tool shown comprises a striking tool 1 and an auxiliary tool 2 combined with the striking tool 1, wherein the striking tool 1 comprises a striking handle 101, a striking head 102 fixedly connected to one end of the striking handle 101 and an elastic grip 103 sleeved on the other end of the striking handle 101, the striking handle 101 is provided with a front end abutting portion 104 and a rear end abutting portion 105 for abutting against both ends of the elastic grip 103, the end of the elastic grip 103 abutting against the front end abutting portion 104 can be extended and retracted along the length direction of the striking handle 101, the front end abutting portion 104 is located between the elastic grip 103 and the striking head 102, the striking handle 101 is also vertically connected with a connecting pin 4 with an end cap 3, the end cap 3 is located at the end of the connecting pin 4 away from the striking handle 101, the outer diameter of the end cap 3 is larger than the outer diameter of the connecting pin 4, and the connecting pin 4 is located between the striking head 102 and the front end abutting portion 104.

[0024] like Figure 2~Figure 4As shown, the accessory tool 2 includes a handle 201, and an oblong stepped hole 202 is opened in the middle of the handle 201. The long diameter L of the stepped hole 202 is parallel to the length direction of the handle 201. The short diameter a at one axial end of the stepped hole 202 matches the outer diameter of the end cap 3, and the short diameter b at the other end matches the outer diameter of the connecting pin 4. The stepped hole 202 is located at the end with the smaller short diameter and radially expands to form a through hole 203 for the end cap 3 to pass through. The through hole 203 is located at the end of the stepped hole 202 far away from the tail of the handle 201 in the long diameter direction. The tail end of the handle 201 is provided with A notch 204 cooperates with the front end of the elastic grip 103, a blocking portion 205 is provided at the front of the handle 201, the step hole 202 is located between the blocking portion 205 and the notch 204, the blocking portion 205 and the notch 204 are respectively arranged on both sides of the handle 201, and the blocking portion 205 extends out of the handle 201 along the axial direction of the step hole 202 toward the end with a smaller short diameter, and the distance between the step hole 202 and the notch 204 is greater than the distance between the connecting pin 4 and the elastic grip 103, so as to ensure that the elastic grip 103 can elastically abut against the inner wall of the notch 204.

[0025] like Figure 5 As shown, when the handle 201 of the accessory tool 2 is inserted into the connecting pin 4 and the handle 201 is rotated until the long diameter of the step hole 202 is parallel to the long diameter of the connecting pin 4 and the through hole 203 is away from the elastic grip 103, the inner wall of the notch at the rear end of the handle 201 elastically abuts against the front end of the elastic grip 103, and the blocking part 205 at the front of the handle 201 is opposite to the side of the knocking handle 101 parallel to the axial direction of the connecting pin 4. The elastic grip 103 pushes the handle 201 forward to move the connecting pin 4 to the side of the step hole 202 away from the through hole 203.

[0026] The striking handle 101 of the striking tool 1 described in this embodiment includes a main body 101a, a front end abutting portion 104, a sleeve rod 101b and a rear end abutting portion 105 connected in sequence. The front end of the main body 101a is connected to the striking head 102, the width of the sleeve rod 101b is smaller than the width of the main body 101a, the front end abutting portion 104 is trapezoidal or frustum-shaped, the width of the large end of the front end abutting portion 104 is consistent with that of the main body 101a and is connected to the rear end of the main body 101a, the width of the small end is consistent with the width of the sleeve rod 101b and is connected to the front end of the sleeve rod 101b, the width of the rear end abutting portion 105 is greater than the width of the sleeve rod 101b and is connected to the rear end of the sleeve rod 101b, the elastic grip 103 is sleeved on the sleeve rod 101b, the elastic grip 103 is formed by spirally winding spring steel, and is in the shape of a jujube with flat ends as a whole, and the front end of the elastic grip 103 abuts on the inclined surface of the front end abutting portion 104.

[0027] The elastic grip 103 may also be made of rubber, but the elasticity of rubber is not as stable as that of a spring, so a spring is preferred.

[0028] like Figure 4 As shown, the notch 204 in this embodiment is preferably opened at the top corner position on one side of the rear end of the handle 201, and a contact surface 5 directly opposite to the front end of the elastic handle 103 and a limiting surface 6 opposite to the side of the elastic handle 103 are formed in the notch 204. After the front end of the elastic handle 103 extends into the notch 204, it is blocked by the limiting surface 6. The limiting surface 6 and the blocking portion 205 respectively limit the accessory tool 2 from rotating clockwise and counterclockwise around the connecting pin 4, thereby locking the handle 201.

[0029] The accessory tool 2 in this embodiment is a brush. In actual application, the type of the accessory tool 2 can be changed according to work needs, such as a wrench.

[0030] In this embodiment, the blocking portion 205 is preferably extended to the side of the striking handle 101 facing away from the connecting pin 4 and is connected to a shovel head 206 , thereby further increasing the functionality of the combined striking tool.

[0031] In this embodiment, the cross-section of the connecting pin 4 is further preferably designed to be an oblong, and the long diameter of the connecting pin 4 is parallel to the length direction of the knocking handle 101. The short diameter of one end of the step hole 202 that cooperates with the connecting pin 4 matches the short diameter of the connecting pin 4. A locking hole 207 with a diameter matching the long diameter of the connecting pin 4 is provided on one side of the step hole 202 close to the rear end of the handle 201. The locking hole 207 is formed by radial expansion of the end of the step hole with a smaller short diameter.

[0032] The cross section of the connecting pin 4 is designed to be an oblong, so that the striking tool and the accessory tool 2 can be connected as follows: Figure 6 In the state shown, the connecting pin 4 is still locked in the locking hole 207. The user can hold the elastic grip 103 and the main body 101a of the striking handle 101 with both hands respectively to push the accessory tool 2 to perform the operation. The two-handed operation can improve the force effect.

[0033] The striking tool 1 in this embodiment is a pickaxe, but may also be a hammer in actual applications.

[0034] The working process of the present invention is: Figure 1 to Figure 6As shown, when the user needs to connect the striking tool 1 and the accessory tool 2 for storage, the user first makes the end of the step hole 202 with a smaller short diameter close to the striking handle 101 of the striking tool 1, and then puts the accessory tool 2 on the connecting pin 4 through the through hole 203, and then rotates the accessory tool 2 to make the tail end of the handle 201 close to the elastic grip 103. When the tail end of the handle 201 contacts the elastic grip 103, the user compresses the elastic grip 103 toward one end of the rear end abutment portion 104 to make the elastic grip 103 avoid the tail end of the handle 201, so that the handle 201 continues to rotate until the blocking portion 205 abuts against the side of the striking handle 101. At this time, the handle 201 cannot rotate further, and the notch 204 is just opposite to the front end of the elastic grip 103. The elastic grip 103 is released, and the front end of the elastic grip 103 extends and inserts into the notch 204 and abuts against the abutting surface 5, pushing the handle 201 to move toward the striking head 102, so that the connecting pin 4 moves to the side of the step hole 202 away from the through hole 203, and the end cap 3 is embedded in the step hole 202 to limit the handle 201 from axially separating from the connecting pin 4, and the limiting surface 6 is opposite to the side of the front end of the elastic grip 103. Figure 5 shown.

[0035] When it is necessary to separate the striking tool and the accessory tool, the user can compress the elastic grip 103 toward one end of the rear end abutment portion 104, and then stand the striking handle 101 upright so that the striking head 102 faces upward. At this time, under the action of gravity, the accessory tool 2 will slide downward along the connecting pin 4, causing the connecting pin 4 to slide into the through hole 203, and then rotate the striking handle 101 to make the notch 204 at the rear end of the handle 201 disengage from the locked position of the elastic grip 103, so that the elastic grip 103 can be released and the accessory tool 2 can be withdrawn from the connecting pin 4.

[0036] The above embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
