Description

TECHNICAL FIELD

[0001] The present application relates to the field of repair tools, in particular to a combined repair hammer. BACKGROUND

[0002] In daily repair work, a hammer is a commonly used tool. However, when an accident occurs outdoors, not only a hammer is used alone, but also a crowbar, a curved scraper and some screwdrivers with long rods are used. These workpieces sometimes need to consume a large amount of force when used, and therefore a hollow sleeve is installed on the back side of the hammer head to be sleeved with a tool such as a crowbar that needs to exert a lever.

[0003] In order to use the crowbar and other tools safely, two limiting holes are arranged on the hollow sleeve, and two through holes are drilled on the crowbar and other tools to be limited by two limiting bolts. In order to facilitate installation, the diameter of the crowbar and other tools is smaller than the inner diameter of the hollow sleeve, and the diameter of the through hole is larger than the outer diameter of the limiting bolt, so that when these tools are used, especially when the crowbar is used, a large shear force is generated on part of the area in the limiting bolt, causing the limiting bolt to be bent and deformed, and the safety in use is poor. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a combined repair hammer to solve the problem of low safety in use after the existing repair hammer is installed with a crowbar.

[0039] Please refer to Figure 2In some examples, the limiting grooves 24 are provided in two, and the two limiting grooves 24 are spaced apart along the second direction 12; the protruding portions 6 are provided in two, and the two protruding portions 6 correspond to the two limiting grooves 24 one by one; and the limiting bolts 5 are provided in two, and the two limiting bolts 5 are arranged in the two limiting grooves 24 respectively. The two limiting grooves 24 and the two limiting bolts 5 can be in the third direction 13, so that the limiting bolts 5 provide greater limiting capacity for the pre-rotation tool, and the connection between the pre-assembly tool 3 and the hammer body 2 is more stable.

[0040] In other examples, the protruding portions 6 can also be provided in three or four.

[0041] Please refer to Figure 2 In some examples, along the second direction 12, the two limiting grooves 24 are arranged on the part of the hammer body 2 close to the opening of the accommodating groove 22. At this time, the solid volume of the side of the hammer body 2 where the hammer head 21 is located can be larger, which helps to ensure the strength, weight and use safety of the hammer itself.

[0042] In some examples, the distance between the limiting groove 24 and the edge of the hammer body 2 can be greater than the diameter of the limiting groove 24, so as to avoid the bolt being torn off the edge of the accommodating groove 22 under stress during use.

[0045] Please refer to Figure 1 and Figure 2 In some examples, along the second direction 12, the length of the hammer body 2 on the side where the handle 1 is located is less than the length of the hammer body 2 on the side where the accommodating groove 22 is located, starting from the axis of the handle 1. The side of the handle 1 where the accommodating groove 22 is arranged is lighter in weight, and the length thereof is greater than the length of the side of the hammer head 21, so that the overall center of gravity of the combined repair hammer is closer to the axis of the handle 1, which helps to reduce the operation difficulty when the hammer head 21 is used for maintenance.

[0046] In some examples, the ratio of the length of the hammer body 2 on the side where the hammer handle 1 is located to the length of the hammer body 2 on the side where the accommodating groove 22 is located can be 4:6, or 5:6 or 4:7.

[0047] Please refer to Figure 1 In some examples, the combined repair hammer further comprises a rubber head 7, which is partially slidably arranged in the accommodating groove 22 and is in sealing connection with the inner wall of the accommodating groove 22.

[0048] In some examples, the rubber head 7 can be a conventional rubber hammer structure, which only needs to be arranged in a detachable structure to meet the use requirements and expected functional needs.

[0049] Please refer to Figure 1 In some examples, along the second direction 12, the length of the part of the rubber head 7 located outside the hammer body 2 is less than the length of the part of the rubber head 7 located in the accommodating groove 22. At this time, the contact area of the rubber head 7 with the inner wall of the accommodating groove 22 accounts for a larger proportion of the surface area of the rubber head 7, so that the rubber head 7 is more stable.

[0050] In some examples, the pre-installed tool 3 comprises a crowbar, a screwdriver handle and a curved scraper handle. The crowbar, the screwdriver handle and the curved scraper handle can all be used outdoors, which has high convenience.

[0051] Please refer to Figure 1 In some examples, along the first direction 11, the end of the hammer handle 1 away from the hammer body 2 is provided with a tapered groove 14. The tapered groove 14 can be easily installed by the pre-installed tool 3 described above, so as to realize the lengthening of the hammer handle 1, and at the same time, the overall weight of the combined repair hammer can be reduced, so that the tool is more comfortable to use.

[0052] For example, a corresponding lengthened handle or a soft handle with a threaded mounting structure can also be provided, so that the combined repair hammer in the present scheme can be more convenient to use outdoors to play a more role.

[0053] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0054] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any change or replacement within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
