Description

Novel multifunctional pointer

Technical Field

The utility model relates to a teaching equipment field relates to a novel multi-functional teacher's pointer particularly.

Background

The teacher's pointer is a stick for teaching teacher to indicate writing and picture. Older teachers used a ring-like instrument for punishing and flagging students. In modern society teaching, whether primary schools or higher colleges, the teacher's pointer is still widely used in the teaching process. The existing pointer is designed to be more traditional, is only a common telescopic rod, is convenient to carry, and only has the function of indicating a blackboard and pictures. The conventional pointer cannot play a role in prolonging the chalk writing range, cannot wipe chalk marks on the blackboard, is single in function when used, can finish large-scale writing and modifying work on the blackboard by matching with other various tools, and is very troublesome to operate.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a novel multi-functional teacher's pointer, not only can instruct blackboard and picture, can play the effect that the extension chalk wrote the scope moreover to can clean the chalk seal of a government organization in old china on the blackboard, the function is various, convenient to use.

In order to achieve the above object, the present invention provides the following technical solutions:

this novel multi-functional teacher's pointer includes the telescopic link, and the thick one end of telescopic link is connected with the handle, and the side of handle is equipped with annular set frame perpendicularly, is fixed with the blackboard eraser on the set frame, and the thin one end of telescopic link is the threaded rod, is furnished with screw-thread fit's screwed pipe on the threaded rod, and the screwed pipe tip is sealed perpendicularly and is equipped with the baffle, and the baffle is kept away from screwed pipe one end and is equipped with pipy chalk sleeve pipe.

As a further optimization of the technical scheme, the telescopic rod and the threaded rod are both made of aluminum alloy and are of an integrated structure.

As a further optimization of the technical scheme, the handle and the sleeve frame are both made of hard PVC plastics and are of an integral structure.

As a further optimization of the technical scheme, the threaded pipe and the partition plate are both made of hard PVC plastics and are of an integral structure.

As a further optimization of the technical scheme, the chalk sleeve is made of rubber materials and is connected with the partition plate through an adhesive.

The beneficial effect of adopting above technical scheme is: this novel multi-functional teacher's pointer can hold the handle when using, pulls open the telescopic link to suitable length, utilizes the threaded rod of front end to instruct characters and picture on the blackboard. The threaded pipe can be screwed on the threaded rod, then the chalk is inserted tightly on the chalk sleeve, and a teacher can hold the handle by hands and remotely control the chalk to write on the blackboard. The teacher can also wave the handle and use the blackboard eraser to erase chalk marks on the blackboard. This novel multi-functional teacher's pointer not only can instruct blackboard and picture, can play the effect of extension chalk writing scope moreover to can clean the chalk seal of a government organization in old china on the blackboard, the function is various, convenient to use.

Drawings

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

FIG. 1 is a front view of the multifunctional pointer of the present invention;

FIG. 2 is a top view of the multifunctional pointer of the present invention;

fig. 3 is the storage schematic diagram of the multifunctional pointer of the present invention.

The chalk box comprises a telescopic rod 1, a handle 2, a chalk sleeve 3, a blackboard eraser 4, a partition plate 5, a sleeve frame 6, a threaded pipe 7 and a threaded rod 8.

Detailed Description

The following describes in detail a preferred embodiment of the multifunctional pointer of the present invention with reference to the accompanying drawings.

Fig. 1, fig. 2 and fig. 3 show the specific implementation of the multifunctional pointer of the present invention:

combine fig. 1, fig. 2 and fig. 3, this novel multi-functional teacher's pointer includes telescopic link 1, and the thick one end of telescopic link 1 is connected with handle 2, and the side of handle 2 is equipped with annular set frame 6 perpendicularly, is fixed with blackboard eraser 4 on the set frame 6, and the thin one end of telescopic link 1 is threaded rod 8, is furnished with screw-thread fit's screwed pipe 7 on the threaded

rod

8, and 7 tip vertical seal of screwed pipe are equipped with

baffle

5, and 7 one end of screwed pipe are kept away from to baffle 5 is equipped with pipy chalk sleeve pipe 3. The blackboard eraser 4 is fixed on the sleeve frame 6 through screws, and the blackboard eraser 4 is positioned on the outer side of the sleeve frame 6 far away from the handle 2.

The telescopic rod 1 and the threaded rod 8 are made of aluminum alloy, and are firm, durable and good in corrosion resistance, and the telescopic rod 1 and the threaded rod 8 are of an integrated structure. The handle 2 and the sleeve frame 6 are both made of hard PVC plastics, so that the handle is firm and durable, the manufacturing cost is low, and the handle 2 and the sleeve frame 6 are of an integral structure. The handle 2 is fixedly connected with the telescopic rod 1 through a screw. The threaded pipe 7 and the partition plate 5 are both made of hard PVC plastic, so that the structure is firm and durable, the manufacturing cost is low, and the threaded pipe 7 and the partition plate 5 are of an integral structure. The chalk sleeve 3 is made of rubber materials, the elasticity is good, the friction coefficient is large, the chalk sleeve 3 can be tightly wrapped and sleeved with chalk, the classroom is convenient to hold the handle 2 to control the chalk to write on the blackboard, and the chalk sleeve 3 is connected with the partition plate 5 through a bonding agent.

This novel multi-functional teacher's pointer can hold handle 2 when using, pulls open 1 to suitable length of telescopic link, utilizes the threaded rod 8 of front end to instruct characters and picture on the blackboard.
