Abstract

The invention discloses an oil sludge scraper with a replaceable cutter head, which comprises a handle and a cutter head module, wherein the cutter head module comprises a cutter bar and a cutter head connected with the cutter bar. The oil sludge scraper further comprises a clamping module, wherein the clamping module comprises a clamping head and a spring clamping head, one end of the clamping head is in threaded connection with the handle, the other end of the clamping head is provided with a round hole capable of holding the spring clamping head, one end of the spring clamping head extends into the round hole to be in threaded connection with the clamping head, and the spring clamping head is internally provided with a holding groove capable of clamping the cutter bar. According to the invention, the cutter grade is improved, the manufacturing cost is lowered, and the oil sludge scraper is convenient to use, store and carry.

Description

technical field [0001] The invention relates to a sludge scraper with a replaceable cutter head. Background technique [0002] The appearance of products such as automobiles, home appliances, and sanitary ware is an important factor affecting product sales. After the graphic design of such products, it is often necessary to make a physical model for comprehensive evaluation. Making a clay model is a common method. [0003] In the design of sludge modeling, many different types of scrapers are needed, such as straight-toothed scrapers, which are mainly used to complete rough scraping on the plane; arc-shaped tooth-edged scrapers, which are mainly used to complete scraping of changing concave surfaces; , is mainly used to complete the scraping of the determined concave surface; the triangular scraper is mainly used to complete the scraping of the handover facet; there are also arc scrapers, egg-shaped scrapers, straight scrapers, fine scrapers, etc. There are different size ...
