Technical Field

[0001] The utility model relates to the technical field of electric hammers, and particularly relates to an electric hammer convenient to use. Background Technique

[0002] An electric hammer is an electric rotary hammer drill with a pneumatic hammering mechanism and a safety clutch.

[0003] In this regard, Chinese Patent Application No.: CN202023091654.X discloses an electric hammer convenient to hold and use, including an electric hammer. A positioning mechanism is provided at the bottom of the electric hammer. The inner walls of the top and bottom of the first cross bar are both processed with sliding grooves. Sliding blocks are slidably connected to the inner walls of the two sliding grooves. One side of the outer walls of the two sliding blocks is fixedly connected with a second cross bar. The outer wall of the second cross bar is in clearance fit with the inner wall of the first cross bar. The right side of the first cross bar is fixedly connected with the left side of the vertical bar. For this electric hammer convenient to hold and use, when using the electric hammer to drill holes in an external object, the sliding connection between the sliding sleeve and the sliding rod enables the first plate body to drive the electric hammer to be vertically placed with respect to the external object, and stable vertical drilling can be performed. The rod body can drive the second plate body to move left and right. Furthermore, when the electric hammer drills to a certain depth, the external object comes into contact with the second plate body, thereby limiting the electric hammer, and further controlling the drilling depth of the electric hammer.

[0004] This electric hammer drives the rod body to move by setting a screw rod, and cooperates with the second plate body to control the drilling depth. However, during the actual use of the electric hammer, it can only drill holes with a fixed depth according to the preset position of the rod body, and cannot make specific adjustments to the depth according to the actual situation during drilling, resulting in limitations in the use of the device.

[0005] Therefore, in order to solve the above problems, an electric hammer convenient to use is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide an electric hammer convenient to use, so as to solve the problem in the prior art mentioned in the above background technique that the electric hammer drives the rod body to move by setting a screw rod, and cooperates with the second plate body to control the drilling depth. However, during the actual use of the electric hammer, it can only drill holes with a fixed depth according to the preset position of the rod body, and cannot make specific adjustments to the depth according to the actual situation during drilling, resulting in limitations in the use of the device.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An electric hammer convenient to use, including: an electric hammer main body, a drill bit is installed at the output end of the electric hammer main body, and a handgrip is fixedly installed in the middle of the electric hammer main body.

[0008] A ranging structure is installed on the handle. The ranging structure includes a fixed ear which is fixedly installed on the upper surface of the handle. A scale rod is fixedly connected to the surface of the fixed ear. Threaded ridges are integrally formed on the outer wall of the scale rod. A hand-rotating ring is threadedly connected to the outside of the threaded ridges. A spring is fixedly connected to the left end of the scale rod. A movable sleeve is sleeved on the outside of the left end of the scale rod. A clamping groove is formed at the left end of the movable sleeve. A collection bag is hooked inside the clamping groove.

[0009] Preferably, two groups of the scale rod and the movable sleeve are provided. The two groups of the scale rod and the movable sleeve are respectively located on the front and rear sides of the electric hammer body.

[0010] Preferably, the threaded ridges penetrate through the movable sleeve. One end of the spring is fixedly connected to the inner wall of the movable sleeve.

[0011] Preferably, the left end of the movable sleeve is flush with the left end of the drill bit.

[0012] Preferably, the collection bag is located below the left end of the drill bit.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By providing a scale rod that can move inside the movable sleeve, during the drilling process, the scale rod can be retracted into the interior of the movable sleeve. By observing the scale on the surface of the scale rod, the depth of the drilled hole can be known in real time during drilling, so as to adjust according to the actual situation, improving the practicability of the device.

[0014] In the present utility model, by providing a ranging structure, both ends of the collection bag are hung in the clamping groove. The movable sleeve can be attached to the drilling surface. The dust generated during drilling can fall downward into the collection bag. When pressing the electric hammer body, the scale rod can be driven to move towards the movable sleeve through the handle and the fixed ear. The movable sleeve is attached to the drilling surface and cannot move. Therefore, the movable sleeve moves on the outside of the scale rod, enabling the scale rod to retract into the movable sleeve and compress the spring, providing guidance for the movement of the electric hammer body. When the drilling is smooth, the movable sleeve moving on the outside of the scale rod can be attached to the hand-rotating ring, and a hole with a predetermined depth can be drilled on the drilling surface. When there are impurities such as metal in the drilling surface, affecting the drilling of the scale rod, the scale rod cannot penetrate the predetermined distance. At this time, by observing the scale on the surface of the scale rod, the depth of the drilled hole can be known in real time during drilling. After pulling out, measures can be taken according to the depth of the drilled hole. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1 - 4 One embodiment provided by the present utility model:

[0022] The electric hammer main body 1, the drill bit 11 and the handle 12 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be described in detail here.

[0023] A convenient-to-use electric hammer includes: an electric hammer main body 1, a drill bit 11 is installed at the output end of the electric hammer main body 1, and a handle 12 is fixedly installed in the middle of the electric hammer main body 1;

[0024] A distance measuring structure 2 is installed on the handle 12. The distance measuring structure 2 includes a fixed ear 21. The fixed ear 21 is fixedly installed on the upper surface of the handle 12. The surface of the fixed ear 21 is fixedly connected with a graduated rod 22. A threaded rib 23 is integrally formed on the outer wall of the graduated rod 22. A hand screw ring 24 is threadedly connected to the outside of the threaded rib 23. A spring 25 is fixedly connected to the left end of the graduated rod 22. A movable sleeve 26 is sleeved outside the left end of the graduated rod 22. A card slot 27 is opened at the left end of the movable sleeve 26. A collection bag 28 is hooked inside the card slot 27. The graduated rod 22 can move inside the movable sleeve 26. During the drilling process, the graduated rod 22 can be retracted into the interior of the movable sleeve 26. By observing the scale on the surface of the graduated rod 22, the depth of the drilled hole can be known in real time during drilling, so as to adjust according to the actual situation, improving the practicability of the device.

[0025] Furthermore, two sets of scale rods 22 and movable sleeves 26 are respectively provided. The two sets of scale rods 22 and movable sleeves 26 are respectively located on the front and rear sides of the electric hammer body 1. The two sets of scale rods 22 and movable sleeves 26 can guide the drilling angle of the electric hammer body 1 on both sides to facilitate vertical drilling.

[0026] Furthermore, the threaded ridge 23 penetrates through the movable sleeve 26. One end of the spring 25 is fixedly connected to the inner wall of the movable sleeve 26. The threaded ridge 23 provides guidance for the straight movement of the movable sleeve 26 outside the scale rod 22 to prevent the movable sleeve 26 from rotating, and the spring 25 provides power for the movable sleeve 26 to reset outside the scale rod 22.

[0027] Furthermore, the left end of the movable sleeve 26 is flush with the left end of the drill bit 11. The distance that the drill bit 11 drills into the drilling surface can act on the movable sleeve 26 through the reaction of the drilling surface, so that the moving distance of the movable sleeve 26 outside the scale rod 22 can be intuitively shown.

[0028] Furthermore, the collection bag 28 is located under the left end of the drill bit 11. During drilling, the collection bag 28 can receive the falling dust to collect the dust and reduce environmental pollution.

[0029] Working principle: Before use, rotate the hand screw ring 24. The hand screw ring 24 is threadedly connected to the threaded ridge 23. When the hand screw ring 24 rotates, it can move outside the scale rod 22 through the threaded ridge 23. According to the predetermined drilling depth, the position of the hand screw ring 24 outside the scale rod 22 can be adjusted, and both ends of the collection bag 28 are hung in the card slot 27.

[0030] During use, hold the handle 12 and press the electric hammer body 1. The rotating drill bit 11 will then spin into the predetermined position. At the same time, the movable sleeve 26 can fit the drilling surface. The dust generated during drilling can fall downward into the collection bag 28. When pressing the electric hammer body 1, the scale rod 22 can be driven to move towards the movable sleeve 26 through the handle 12 and the fixed ear 21. The movable sleeve 26 fits the drilling surface and cannot move. Therefore, the movable sleeve 26 moves outside the scale rod 22, causing the scale rod 22 to retract into the movable sleeve 26 and compress the spring 25, which can provide guidance for the movement of the electric hammer body 1.

[0031] When the drilling is smooth, the movable sleeve 26 moving outside the scale rod 22 can fit the hand screw ring 24, and a hole with a predetermined depth can be drilled on the drilling surface. When there are sundries such as metal in the drilling surface, which affects the drilling of the scale rod 22, the scale rod 22 cannot penetrate the predetermined distance. At this time, by observing the scale on the surface of the scale rod 22, the depth of the drilling can be known in real time during drilling. After pulling out, measures can be taken according to the depth of the drilling.

[0032] The above are only the preferred embodiments of the present utility model, and do not impose any formal restrictions on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to the illustrations in the specification and the above description; however, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the substantial technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
