Description

TECHNICAL FIELD

[0001] The utility model relates to the chisel technical field, concretely is a general chisel. BACKGROUND

[0002] In many fields such as building construction, decoration, stone processing, chisel is a commonly used tool, often need to cooperate with electric shovel or pneumatic shovel (power equipment to improve work efficiency.

[0003] At present, the general chisel of existing mostly is the chisel head and handle structure of integral molding, the end of handle far away from chisel head has the connecting section for connecting with power equipment. Because the working principle and design features of electric shovel and pneumatic shovel are different, their connecting mode with chisel also exists difference. The end of chisel adapted to electric shovel and pneumatic shovel adopts different structure to connect, which leads to the chisel used by electric shovel and pneumatic shovel cannot be mutually adapted, and electric shovel and pneumatic shovel need to adapt different chisel respectively. For example, GB / T 17907-2020 "pneumatic tool connecting size" standard stipulates that the handle connecting section of pneumatic chisel needs to set circular step structure, and the end face of step and the transition of handle need to be rounded, and the length range of connecting section is limited to 40-55mm. According to GB / T 22678-2022 "electric tool chisel class accessory general technical conditions", the connecting section of electric chisel must adopt double-face symmetrical slot structure. For example, the new type chisel adapted to electric shovel disclosed in application number CN201921710774.8, and the dual-purpose pneumatic shovel of application number CN201821496447.2.

[0004] When the operator faces the situation of using electric shovel and pneumatic shovel simultaneously in actual work, different types of chisel need to be prepared to adapt to the two kinds of equipment. This not only increases the procurement cost and management difficulty of tools, but also wastes time when changing tools, and reduces work efficiency.

[0005] In order to solve the above problems, the application provides a general chisel. UTILITY MODEL CONTENTS

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0023] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0024] The utility model provides a general chisel.

[0025] In the embodiment, with reference to Figs. 1-2 The general chisel comprises an integrally formed chisel head 1 and handle 2, the end of the handle 2 away from the chisel head has a connecting section 3, and the connecting section 3 is provided with a circular step 4 for connecting with a pneumatic shovel and a connecting structure for connecting with an electric shovel.

[0026] In the above technical solution, the circular step for connecting with the pneumatic shovel and the connecting structure for connecting with the electric shovel are arranged on the connecting section, so that the chisel can be adapted to both the electric shovel and the pneumatic shovel, greatly improving the versatility of the chisel. Different chisels are not needed for different equipment, reducing the number and types of tools, reducing the tool procurement cost and management difficulty, and facilitating the quick switching of the operator between different equipment, improving the work efficiency.

[0027] Specifically, rounded corners 5 are arranged between the circular step and the handle and between the circular step and the connecting section.

[0028] In the embodiment, the rounded corners 5 are arranged between the circular step 4 and the handle 2 and between the circular step 4 and the connecting section 3, which can effectively avoid stress concentration.

[0029] Specifically, the diameter of the circular step is 16-22mm.

[0030] In this embodiment, the diameter of the circular step is limited to 16-22mm, which can be matched with the connection part of most pneumatic shovels on the market, ensuring the stability and reliability of the connection between the chisel and the pneumatic shovel. The appropriate diameter size can make the circular step tightly fit in the connecting device of the pneumatic shovel, and it is not easy to loosen or fall off during work, ensuring the safety and continuity of work during use, and improving the work efficiency. More specifically, the diameter is 16mm, 18mm and 20mm.

[0031] Specifically, the diameter of the connecting section is 8-11mm.

[0032] In this embodiment, the diameter of the connecting section is set to 8-11mm, which can ensure that the connecting section itself has sufficient strength to withstand the power transmission from the electric shovel or pneumatic shovel during use and various forces generated during work, and is not easy to break or deform. On the other hand, this diameter range is also matched with other connection structures (such as the structure connected with the electric shovel) on the connecting section, so that the connection is more stable. The diameter of the connecting section is more specifically 9mm and 10mm.

[0033] Specifically, the length L of the connecting section is 35-60mm.

[0034] In this embodiment, the length of the connecting section is limited to 35-60mm, which can provide sufficient space and length for the connection between the chisel and the electric shovel or pneumatic shovel, ensuring the firmness of the connection. The appropriate length can make the connection structure (such as the slot and the connecting concave surface connected with the electric shovel) fully function, and tightly fit with the connecting parts of the power equipment. At the same time, this length range also takes into account the balance of the chisel as a whole and the convenience of operation, and will not affect the use feeling and work efficiency of the chisel because of the too long or too short connecting section. The commonly used length of the connecting section on the market is more specifically 40mm, 43mm, 45mm and 47mm.

[0035] Specifically, the connecting structure includes a slot 6 arranged on the upper and lower sides of the connecting section and a connecting concave surface 7 arranged on the left and right sides of the connecting section.

[0036] In this embodiment, the slot on the upper and lower sides of the connecting section and the connecting concave surface on the left and right sides of the connecting section jointly constitute the connection structure with the electric shovel, which can form a tight fit with the connecting parts of the electric shovel.

[0037] Note: Although the utility model has been described according to the above specific embodiments, the utility model idea is not limited to this utility model, and any modification using the utility model idea will be included in the patent protection range.
