[0002] A down-the-hole drill is a device used to drill holes in rocks before blasting. It is often used in water conservancy projects. The existing down-the-hole drills are of two types: internal combustion and electric. Depending on the hole diameter, down-the-hole drills can be divided into light down-the-hole drills, medium down-the-hole drills, and heavy down-the-hole drills. Light down-the-hole drills are smaller in size and relatively lighter in weight, making them easy to hold and more convenient to use.

[0003] Traditional handheld down-the-hole drills are usually only equipped with two sets of handles during use and can only be held by one person. During drilling, the vibration generated by the equipment is relatively large, and one person cannot stably control the equipment, which can easily cause the position of the hole to shift and affect the accuracy of the hole. In view of this, we propose a down-the-hole drill that is easy to hold and use with water. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3 The utility model provides a water-use convenient handheld down-the-hole drill, comprising a mounting base 1, a motor 2 is fixedly connected to the surface of the mounting base 1, the output shaft of the motor 2 passes through and is rotatably connected to the bottom surface of the mounting base 1, a connecting shaft 3 is fixedly connected to the output end of the motor 2, a drill bit 4 is fixedly connected to the end of the connecting shaft 3, and the connecting shaft 3 is rotated by the motor 2, so that the connecting shaft 3 drives the drill bit 4 to drill, thereby performing a hole drilling work, and a handheld component 5 is fixedly connected to the side wall of the mounting base 1.

[0022] In the embodiment of the utility model, the handheld component 5 includes:

[0023] A fixing rod 51, the fixing rod 51 is fixedly connected to the side wall of the mounting seat 1, two groups of fixing rods 51 are provided, and the fixing rods 51 are symmetrically arranged with the transverse center line of the mounting seat 1 as the symmetry axis, and the top of the fixing rod 51 is fixedly connected to a hand-held rod 52;

[0024] And there are four groups of rings 53 , and the four groups of rings 53 are all sleeved on the surface of the hand-held rod 52 , and a strap 54 is fixedly connected to the surface of the rings 53 .

[0025] Specifically, in the embodiment of the utility model, the hand-held assembly 5 includes a fixed rod 51, a hand-held rod 52, a ring 53, and a strap 54. The hand-held rod 52 is shaped like a frame. Two groups of fixed rods 51 are provided. The hand-held rod 52 is fixedly connected to the mounting base 1 through the two groups of fixed rods 51, so as to facilitate hand-holding. Since the shape of the hand-held rod 52 is set to be frame-shaped, the hand-held rod 52 can be held by two people at the same time for work, and the ring 53 and the strap 54 cooperate with each other to entangle the user's hand with the hand-held rod 52, so as to avoid the equipment from vibrating violently during operation, and the hand is prevented from being separated from the hand-held rod 52, causing the equipment to fall off.

[0026] In the embodiment of the utility model, the outer wall of the fixed rod 51 is provided with a protective component 55, and the protective component 55 includes a rubber tube 551, and the rubber tube 551 is fixedly connected to the outer wall of the hand-held rod 52. The interior of the rubber tube 551 is hollow, and the surface of the rubber tube 551 is provided with a plurality of groups of air holes 552 distributed in an array. A sponge cover 553 is fixedly connected to the surface of the rubber tube 551, and the rubber tube 551 cooperates with the rubber tube 551 to protect the user's hand and avoid damage to the hand holding the hand-held rod 52. The sponge cover 553 is distributed in an array on the surface of the rubber tube 551 and has a certain thickness, so that there is a certain gap between the hand and the rubber tube 551, so that when the equipment is working, the hand is vibrated to the rubber tube 551. The rubber tube 551 is squeezed, resulting in the flattening of the rubber tube 551, and the gas is blown toward the palm of the hand through the air hole 552 to prevent the palm from sweating. A protrusion 554 is fixedly connected to the inner wall of the rubber tube 551, and a slide plate 555 is slidably connected to the inside of the protrusion 554.

The top of the support rod 557 is fixedly connected to the inner wall of the rubber tube 551, and the slide plate 555 is rebounded by the return spring 556, so that the inner wall of the rubber tube 551 is supported by the support rod 557, so that after the rubber tube 551 is compressed, the rubber tube 551 can quickly return to its original state.

[0027] In addition, in order to prevent the position of the turning hole from being easily offset and affecting the accuracy of the turning hole, the shape of the hand-held rod 52 is set to be a frame shape, so that two people can hold the hand-held rod 52 at the same time to work, and through the cooperation of the ring 53 and the strap 54, the user's hand and the hand-held rod 52 are entangled together, thereby improving the stability of the equipment when working.

[0028] In order to protect the hands of the staff, the rubber tube 551 cooperates with the rubber tube 551 to protect the hands of the user and avoid injuries to the hands holding the handle 52, and the sponge cover 553 is distributed in an array on the surface of the rubber tube 551 and has a certain thickness, so that there is a certain gap between the hand and the rubber tube 551, so that when the rubber tube 551 is compressed, the air hole 552 can blow the gas to the palm to avoid sweating of the palm.

[0029] In the utility model, when in use, the user's hand is entangled with the hand-held rod 52 through the cooperation between the ring 53 and the strap 54, and the motor 2 connects the shaft 3 to rotate, so that the connecting shaft 3 drives the drill bit 4 to drill, thereby performing drilling work, and the rubber tube 551 cooperates with the rubber tube 551 to protect the user's hand to avoid damage to the hand holding the hand-held rod 52, and the sponge sleeve 553 is distributed in an array on the surface of the rubber tube 551 and has a certain thickness, so that there is a certain gap between the hand and the rubber tube 551, so that when the equipment is working, the rubber tube 551 is squeezed by the vibrating hand, causing the rubber tube 551 to be flattened, and the gas is blown to the palm of the hand through the air hole 552 to avoid sweating in the palm of the hand.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
