When the plastic parts need to be connected to each other, and the dimensions of the two plastic parts in the height direction are relatively large, if the plastic parts are forcibly connected together in the existing way, the structure and function of the plastic parts will inevitably be affected. For example, as shown in FIG. 3 , the upper housing cover 17a and the lower housing cover 17b of the ice drill 10 need to be connected together to form a space for accommodating the driving device 14 and the transmission structure 13 . In some embodiments, the The height of the lower case cover 17b is greater than 100 mm. For such a height dimension, it is not acceptable if the draft angle is not given when the mold is ejected.

The frame is also tightly fastened by the concave or convex buckles set at both ends, which prevents the connection frame from shaking up and down or left and right, which not only meets the assembly requirements, but also does not affect the function of the device, and also facilitates manual assembly and improves the work. efficiency.

In the ice drill of the embodiment of the present invention, the structure for carrying the driving device and the transmission structure is a bracket. At present, most of the supports used for supporting ice drills produced in China are metal bending pipes. However, the ice drill of this embodiment adopts a bracket of plastic material as the supporting structure of the driving device and the transmission structure, which has the advantages of changeable shape and light weight.

Referring to FIG. 7a , it is a schematic structural diagram of a bracket of an ice drill according to an embodiment of the present invention.

Specifically, the control switch 19 may be a forward/reverse switch, which is used to control the rotation direction of the drill pipe 11 , and a button of the control switch 19 is provided on one handle 124 of the bracket 12 , and the other The side handle 124 is provided with the button of the power switch 15 .

In addition, considering that when using ice drills for ice drilling operations on ice, it is easier for people to slip while standing on the ice. Even if they wear anti-skid skates, they are not enough to prevent slipping. When drilling ice, a large force is required to grasp the ice drill. . If the ice drill fails to catch the ice drill when a person applies force, the ice drill will slip and spin with the person or throw the person away, resulting in injury to the human body; on the other hand, after the staff drills the ice, the ice drill needs to be placed on the ice , the ice drill is also easy to slip on the ice. If the ice drill is just placed next to the drilled ice hole, and the diameter of the ice hole is large enough, the ice drill is very easy to slip into the ice hole, causing the safety loss of the ice drill itself.

In order to solve the above problem, the ice drill of the embodiment of the present invention further includes an ice grabbing structure, at least one ice grabbing structure is provided on the bracket, and each ice grabbing structure is used when the ice drill is placed on the ice surface. , increasing the friction between the ice drill and the ice surface.

Referring to Fig. 7b, it is a top view of the support of the ice drill according to the embodiment shown in Fig. 7 of the present invention. The ice-catching structure 125 is semi-circular and includes a wide surface 125a and a pointed portion 125b. The ice drill may include two ice grabbing structures 125, which are arranged on the bracket 12 on the side of the ice drill facing the human body and are located on both sides of the human body respectively. The two sides of the semicircle form the wide surface 125a, and the edge of the semicircle gradually becomes thinner and sharper to form the pointed portion 125b.

Wherein, when the ice drill is working, the tip portion 125b faces the human body, which can provide a support point for the human body to rely on, which is helpful for people to apply force, and the body can rely on this surface to drill ice when drilling ice; When the ice drill is not working and placed on the ice surface, the tip portion 125b is in contact with the ice surface at a certain inclination angle, so that the two ice grabbing structures 125 on the bracket 12 can tightly grasp the ice surface, That is, the friction force between the ice drill and the ice surface is increased, so that the whole ice drill stays on the ice surface, so as to ensure the safety of the ice drill itself.

The ice grabbing structure of this embodiment facilitates the operation of personnel, ensures personal safety, and reduces the safety loss of the ice drill itself.

At present, most ice drills on the market are not equipped with night lights, because most people think that ice drilling operations are mostly carried out during the day. The miner's lamp on the head, or find another person holding a searchlight standing by to help illuminate, these solutions not only waste manpower, but also fail to achieve the desired lighting effect. For the solution of wearing a lamp on the head, there is a problem that the actual situation of the ice surface cannot be illuminated. Because the lamp on the head is far away from the ice surface, the entire ice drilling machine almost completely blocks people's sight. The situation is not understood, once the ice cracking or ice breaking occurs during the ice drilling, it will endanger personal safety.

The inner concave surface of the reflector 126b focuses and reflects light on the transparent lens 126c, and the light beam shines on the ice surface and the drill pipe through the transparent lens 126c, so that the operator can know the actual situation of drilling the ice in real time. In other words, it can also observe the condition of fish under the ice in real time, which satisfies the fun of ice fishing at night, and increases the practicality of the ice drill.

In some embodiments, the light 126 is controlled by the power switch 15 (as shown in FIG. 3 ), the light 126 is turned on when the power switch 15 is turned on, and the light 126 is turned off when the power switch 15 is turned off.

The ice drill of this embodiment includes a lighting lamp, so it can not only grasp the actual situation of ice drilling in dark conditions, but also save manpower, solve a major deficiency of the ice drill lacking lighting when drilling ice at night, and increase the work of the ice drill Scenes.
